Survey of Energy Resources 2007
Solar Country Notes
The average annual insolation in Finland is 1 150 kWh/m2. The seasonal variation of solar radiation in Finland is large; the main part of solar radiation is obtained between March and September.
The sum of installed photovoltaics is 4.0 MWp, of which 95% consists of local PV systems in summer houses, etc., mostly small units in the range of 50-100 Wp. Recently, two somewhat larger installations have been made in Viitasaari (5 kWp) and Saarijärvi (6 kWp).
Whilst the PV sector remains fairly modest, the Ministry of Trade and Industry's Action Plan contains a national target of 40 MWp installed PV capacity by 2010, with a corresponding 2025 level of 500 MWp.
The total glazed area of solar thermal collectors in operation in 2005 was
14 000 m2, giving an output capacity of about 10 MWt.
